Suppose you have a double Debit/Credit card issued in Poland and you're doing typical shopping for €10 on your way home. You use your card, it presents itself as a debit card, which means that the maximum transaction fee is capped at 0,2% as per EU regulation in effect since mid-2015, so you're paying whole two cents for that transaction. Truly life-changing amount of wealth.

Suppose that you're average Johan and your net salary is €2830. Let's assume that half of that is spent on various types of shopping - this means you spend €1415 a month, which means that each month the card company takes €2,83 from you. I don't know what about you, but if I had €2,83 extra each month, I'd immediately feel ultra-rich.

My Dutch bank account costs €4,30 while my Polish bank accounts are free.

You might say "but anal_reactor, what if tragedy happens and the card shows itself as a credit card, not a debit card?"

I have to admit, you have a point. These fees can be 50% higher capped at 0,3% which means that such average Johan would spend €4,25 on card fees each month. As we all know, €4,25 is more than €4,30 by "negative five cents".

I'm sorry, but if "credit cards are expensive" is your best argument against dual Debit/Credit cards working in NL then you are truly retarded and god be my witness I'm stating this as a fact, not an insult.
